Many inquiries start after a diagnosis—often something serious that leads to new questions about past exposures. In Ontario, common triggers include:
- Homeowner or gardener exposure while treating lawns, driveways, and weeds along fences and walkways
- Property maintenance work for HOAs, commercial lots, or facilities where herbicides are applied seasonally
- Work-related exposure in landscaping crews, groundskeeping roles, or maintenance teams supporting industrial properties
- Secondhand exposure where residue may come home on clothing or gear after an application day
Because Ontario’s daily life is shaped by commuting and property turnover, people sometimes only connect the dots later—after a doctor’s assessment, a family member’s diagnosis, or new medical information prompts them to review earlier product use.
